NoClassDefFoundError：org / testng / TestNG [英] NoClassDefFoundError: org/testng/TestNG

问题描述

此错误

NoClassDefFoundError：org / testng / TestNG

NoClassDefFoundError: org/testng/TestNG

当我尝试使用IntelliJ IDEA从Testng.xml文件运行测试时，会出现

。
逐个运行我的测试，以及运行指向 testng.xml 的整个gradle项目，如 grade core-test ：test

appears when I'm trying to run my test from Testng.xml file using IntelliJ IDEA. Running my test one by one works perfectly as well as running whole gradle project which points to testng.xml, like grade core-test:test

（在我的项目中我使用的是Appium + IntelliJ + TestNG）

( On my project I'm using Appium + IntelliJ + TestNG )

但是当我使用IntelliJ运行testng.xml时，我在按下Run后立即收到此消息：

But when I'm running testng.xml using IntelliJ I'm immediately getting this message after pressing Run:

我在这里找到了一个解决方案： https://intellij-support.jetbrains.com/hc/en-us/community/posts/206597869-Cannot-发布 - NGTest-runner-in-IntelliJ-IDEA-2016-1

I found a solution posted here: https://intellij-support.jetbrains.com/hc/en-us/community/posts/206597869-Cannot-launch-NGTest-runner-in-IntelliJ-IDEA-2016-1

我通过选择In来实现它在TestNG运行/调试
配置的配置选项卡下，整个项目（我选择了单个
模块）。

I got it to work by selecting "In whole project" (I had "In single module" selected) under the Configuration tab in the TestNG "Run/Debug Configurations."

但是，先前的配置在IntelliJ IDEA 15中有效，对我来说，
似乎它可能来自于新IDE的重大改变。 / p>

However, the prior configuration worked in IntelliJ IDEA 15, so to me, it seems that it may have come from a breaking change with newer IDE.

它对我有用。
